Carbon nanotubes (CNTs), obtained by rolling up a hexagonal graphene sheet, are a class of 1D nanostructures with many interesting properties that make them promising materials for various technologies, such as energy storage, sensing, composites, and so on. In addition to pure graphitic sheets, compound sheets of boron, carbon, and nitrogen atoms have been produced experimentally.1,2 These BCN monolayers, with atomic compositions such as BN, BC2N, and BC3, have a range of electronic behavior that can be tuned for specific applications
